The poll released Tuesday night found that Paul Davis leads incumbent Sam Brownback 48-40 with 5 percent of respondents saying they support Libertarian Keen Umbehr. The poll found that voters who say education is their top issue favor Davis by 43 percent.

The Survey USA poll also finds that independent Greg Orman has moved to take 20 percent of the vote in the U.S. Senate race with Republican incumbent Pat Roberts at 37 percent and Democrat Chad Taylor at 32 percent.

The poll found that incumbent Secretary of State Kris Kobach is in a 46-46 tie with challenger Jean Schodorf.

How much stock do you place in political polls like these? Are they an accurate reflection of current voter sentiment, or is there considerable room for error? Should the incumbents be nervous about not being further ahead (or ahead at all) at this point in the election cycle?
